The paper focuses on the estimation of multiple Network Fundamental Diagrams (NFDs) associated with clusters obtained after the partitioning of an urban transport network. At this stage, the network is partitioned according to the criterion of the spatial distribution of urban activities, in order to estimate NFDs for the centre and suburbs of the urban area. These operations are necessary to reduce the variance of link densities within each cluster, ensuring that the hypothesis of existence that a homogeneously shaped (with no hysteresis) NFD holds. The experimentation is developed in the town of Villa San Giovanni, in southern Italy. The preliminary results show that the shape of the NFDs seems to depend on the spatial distribution of travel demand.
